Earthquake!
We had an earthquake this morning. M4.4 centered near Fontana. This wasn’t a Big Deal as these things go, but it did make for a busy morning at my office. The non-seismologists at Caltech tend to measure earthquakes by the ‘news truck’ scale, and by that measure, this was only a ‘two truck’ earthquake. Still, it made a traffic spike on the Earthquake Hazards Program web servers, and generally made things busy for a while.
